Fig. 10 is a plan view of an exhaust plate for the device.

In the drawings, reference character I indicates an inlet pipe for castor beans and this pipe extends into a conduit 2 that is provided with a ring having an arm 3 attached thereto. A jack 4 is provided. This jack has a piston rod 5 that is connected to a slot 4 in the arm 3. An inlet 6 and an outlet 1 are provided for fluid that is used for operating the piston rod 5. A support 8 (Fig. 1) is provided for the jack 4 and other parts are mounted on this support as shown. Standards 9 are provided for the support 8 and a base I0 is provided for the standards 9.

A cylindrical member l2 extends through an opening in the support 8 and is supported on the support 8 by flange I3. Arcuate openings M are provided through the lower enlarged end or press head l5 of the cylindrical member l2. Side outlets l6 (Fig. 2) are provided along opposite sides of the lower end of the conduit 2. Diametrically spaced extensions I! are left at the lower end of this conduit. A cross-piece [8 extends across the lower end of the conduit 2 and has a central opening through which'a bolt 2 l9 extends. The threaded conically-shaped portion [9 of the bolt I9 carries a thick disk that is provided with arcuate openings l4 that can be brought into alignment with openings [4.

A vertically movable cylinder or container 2|, in which the enlarged end It of the cylindrical member l2 fits, is operated by hydraulic jacks 22 and pistons 22' on opposite sides of the container 2!. A horizontally movable cylindrical container or pct 25 is provided with perforations 26 through the side wall thereof. This pot rests upon a support 2'! that can be moved up and down. A circular groove 28 is provided along the top side of the support 2'! outside of the pot 25. An outlet pipe 29 extends from the groove 28 for the oil.

A hydraulic jack 30 (Fig. 1) is anchored in position. It is provided with a push rod 3| and a pivot plate 32 for pushing the container 25 out after oil has been pressed out of the beans. Hydraulic jacks 22 are provided on opposite sides for raising the cylinder 2|, when desired.

A support 34 is provided upon which the container 25 is movable by jack 30. An outlet 35 is provided for the pulp. A ram or movable member 31 is provided with arms 38 for removing the residual pulp in container 25 after the oil has been pressed out of the beans. A jack 39 is provided with an inlet to and an outlet 4| for operating the ram 31.

A valve casing 44 (Fig. 6) is provided with a series of inlets and outlets for compressed air. The inlet is shown at 65 and the outlet at 45. Other similar inlets and outlets are provided as shown by Figs. 7 and 8, somewhat diagrammatically. A thick disk 4'! is clamped by bolts 48 in the casing M. An inlet plate 50 and an outlet plate 5| are located in the casing 44. These plates are revolvable and driven by a shaft 52 which carries cross-pins 52a and 52b to drive these plates. An air conduit 53 extends inwardly from the edge of the disk 41. An opening 54 is provided through the disk 4! at right angles to the conduit 53 at the inner end thereof. This opening 54 terminates in a smaller opening 54'. An annular groove 56 is provided along the lower side of the disk 41 starting at the lower end of the opening 54 and terminates short of a circle. An arcuate groove 53 is provided in the lower side of the disk 41 outside of and overlapping the ends of the groove 56. A wheel "59 (Fig. 5) is driven by a motor, not shown. This wheel is attached to the shaft 52 so that the intake plate 50 and exhaust plate 5| are driven in synchronism. The plate 50 is 3 provided with holes 50a, 50b and 500 (Fig. 9) extending therethrough. The disk is provided with holes 5|a to 5| h (Fig. therethrough.

The flanged disk 65 (Fig. 6) is fixedly attached to the shaft 52 and revolves with it. The hub 66 on disk 5| is driven by the shaft 52. A crosspin 52b extends through this hub and shaft. A compression spring 64 keeps the disks 50 and 5| in sliding contact with the thick disk 4']. The contacting surfaces of the disks 41, 50 and 5| are smooth and are spring-pressed together by the spring 64, but the disks 50 and 5| can be re volved by the shaft 52.

The operation is as follows:

With the parts in the position shown in Fig. 1 and shaft 52 being revolved in any convenient way, air under pressure is applied to the jacks 22 and 22a (Figs. 1 and 5) through line 23, thus holding the cylinder 2| a short distance above the pot 25. This occurs due to the fact that compressed air is supplied through inlet 45 (Fig. 6) and passes through hole 501) (Fig. 9) in plate 5|! into groove 58 in the fixed disk 4! (Figs. 6 and '7) and out of the conduit 53b and through line 23 into jacks 22, 22a, thus holding the cylinder 2| in its upper position.

As soon as the plate 5|! has been turned to the position where groove 58 (Fig. 7) does not communicate with inlet 45 through hole 5%, the air pressure is cut off and communication is established by the conduit 53b, openings 54 and 54' in the disk 41 and outlet hole 5|h (Fig. 10) in plate 5| and thence through outlet 46, thereby releasing pressure in the jacks 22 and 22a and permitting the cylinder 2| to descend and rest upon the pot 25.

The next step is opening of the valve I l (Fig. 2) by means of jack 4 (Fig. 5) to feed beans to the pot 25. This opening of the valve occurs when the hole 500 in plate 50 reaches the hole 62 (Fig. 7) in plate 41, and continues until this hole 550 reaches the hole 63 in the stationary plate 4?. At this stage pct 25 has been filled and cylinder 2| is partially filled and the piston 5 (Figs. 2, 3 and 5) is thereby moved to close the valve i4 because air enters jack 4 through line 6. The hydraulic jack 33 is then operated in the, known way by opening a valve by hand or power to raise the support 2?, cylinder 2| and pot 25, thus causing the oil to be pressed out of the beans and flow into groove 28 and through outlet pipe 29 to storage. The jack 33 is then lowered to the position shown in Fig. 1 by opening another valve by hand or power.

After the pots reach this lowered position, the upper cylinder 2| is raised by fluid such as air under pressure entering inlet 45 (Fig. 6) and passing through hole 532) (Fig. 9) in plate 50 which is then aligned with groove 58 in the fixed plate 41 (Fig. 7) and thence into jacks 22', 22a (Fig. 5), thus moving cylinder 2| to its upper position. The jack 3%] is then operated to push the pot 25 out. This is done by the hole 500 (Fig. 9) reaching the outlet 59 (Fig. 8), thus admitting air under pressure to the right-hand end of jack 30 (Fig. 5).

The ram 37 is then lowered when the hole 550 (Fig. 9) reaches the outlet 5|] (Fig. 8) compressed air being thereby admitted through pipe 4!) (Fig. 5') into the upper end of the cylinder 39. This lowering of the ram forces the pulp from pot 25. The ram 31 is then raised when the hole 50a (Fig. 9) reaches the outlet 54 (Fig. '7) compressed air being thereby admitted through pipe 4|. During the remainder of the operating. cycle, the

ram 31 is maintained in the raised position, since the hole 50a in plate 50 mates all this time with groove 56 in the thick stationary disk 41, thus permitting air under pressure to pass out through the corresponding conduit 53 (Fig. 7) in disc 41, and into pipe 4| and then into the lower end of the jack 39 (Fig. 5).

When the hole 500 in plate 50 reaches hole 6| (Fig. '7) in disc 41, the jack 3!! is then operated to return the pot 25 to pressing position. The cylinder 2| then descends and rests upon the pot 25, the air pressure in the jacks 22 and 22a being released via air conduit 53, opening 54 in the disc 41, outlet hole 5|h (Fig. 10) in plate 5|, and outlet 46. When the hole 500 reaches hole 62 compressed air enters the jack 4 (Fig. 5) through the pipe I, thus opening the gate I4, and thereby permitting seed to flow into the pot 25 and cylinder 2|. When the hole 500 reaches hole 63, compressed air enters the jack 4 through the pipe 6 and closes the gate l4, thereby cutting off the flow of seed into the pot 25 and cylinder 2 l, which are filled with seed at this stage.

So long as the hole 50a mates with the groove 56 air goes through the hole 50a and groove 56 to the port hole 53 and then to the lower end of the jack 39 (Fig. 5) to keep the ram 31 in its upper position. In order to raise the cylinder 2|, air is caused to enter the hole 501; in the disk 50 and the groove 58, then out through another porthole 53b in the thick disk 47. The cylinder 2| is then in its upper position.

When the hole 500 in disk 50 reaches the hole 59 in the stationary disk 47, air forces the piston 3| out to push the pot 25 out.

When the hole 500 reaches the hole 60 in disc 41 air is cut 01f from the out through an outlet 60' to the inlet 40 at the upper end of jack. 39, the ram thereby being lowered. Immediately afterward, when the hole 500. reaches the groove 56, air again enters the pipe 4| to raise the ram.

When the hole 500 reaches the hole 6|, air passes out through the outlet 53c, in disk 41 to the pipe 30' of the jack 30.

When the hole 50b passes the end of the groove 58 air is cut off so that the cylinder 2| descends by gravity.

As shown by Figs. 7 to 10, when the hole 50c registers with the hole 59, a hole 5| d (Fig. 10) registers with the hole 6| of the disk 47. When the hole 50c registers with the hole 60, the hole 5H1. registers with the groove 56 in the disk 41. When the hole 55a first registers withthe groove 56, the hole 5|c registers with the hole 60in disk .47, and when the hole 500 registers with the hole 6|, the hole 5|b registers with the hole 59 in the disk 41, so that the sequence of events occurs as explained. It is to be understood that the holes 5|a-5|h are the holes through which the compressed air is vented after being used for operating the several jacks.
